OpenRPC MCP Server 工具

Call any JSON-RPC method on a server with parameters. A user would prompt: Call method <method> on <server url> with params <params>

This uses JSON-RPC to call `rpc.discover` which is part of the OpenRPC Specification for discovery for JSON-RPC servers. A user would prompt: What JSON-RPC methods does this server have? <server url>

概览

What is OpenRPC MCP Server?

The OpenRPC MCP Server is a Model Context Protocol server that provides JSON-RPC functionality through the OpenRPC specification. It allows users to call arbitrary JSON-RPC methods and discover available methods on any JSON-RPC server.

How to use OpenRPC MCP Server?

Install with npm install, build with npm run build, and configure as an MCP server in Claude Desktop by adding the provided JSON to the desktop config file. Run with npx -y openrpc-mcp-server. The server exposes two tools: rpc_call and rpc_discover.

Key features of OpenRPC MCP Server

rpc_call tool for calling any JSON-RPC method
rpc_discover tool to discover methods via OpenRPC
Built on the OpenRPC specification
Easy integration with Claude Desktop
Supports development with npm scripts

Use cases of OpenRPC MCP Server

Call arbitrary JSON-RPC methods from an MCP client
Discover all available methods on a JSON-RPC server
Automate JSON-RPC interactions within a Claude workflow
Debug and test JSON-RPC endpoints using MCP tools
